Vinegar retards the growth of mold. When we would return, the boat still was fresh. After finding mold on a chunk of cheese I decided to try a little experiment. I took a paper towel and folded it down to about a 2 x 2 inch square. I then dampened the paper towel with vinegar. Barely damp, just enough that you can tell it is damp. I then wrapped my cheese in the paper towel and placed inside a Ziploc bag and returned to the refrigerator.
I have never had cheese mold on me again and I have not wasted a bite. If your paper towel begins to dry out, all that you need to do is to redampen the towel with vinegar. The small amount that you are using doesn't leave a vinegar taste to the cheese. Buying cheese in "chunks" is cheaper than the already shredded and will save you a bit of money in addition to no more moldy cheese. Cheese will last for weeks stored this way. Hope you will give this a try because it certainly does work.

I buy 5 lb. bags of shredded mozzarella cheese because my family makes pizza on a regular basis. However, once the bag is opened, it tends to begin to mold fairly quickly. Has anyone used a variation of this vinegar method with shredded cheese? If this doesn't work, does anyone have a suggestion?

I keep all hard cheese in the freezer, shredded cheese lasts months longer. I once received a 20 lb. block of white cheddar and after giving away at least half of it, I hacked the rest into smaller blocks and it kept in the freezer for over a year. Hope this helps!
Can you use white vinegar instead of cider vinegar to stop moulding?

First dampen paper towel with apple cider vinegar then wrap around the block of cheese. Then wrap in foil and place in zipper type baggie.
This will keep the cheese for a couple of months without getting mold. The vinegar does not leave a taste on the cheese.
